Formula Field Need help finding 3rd party who can provide

I am shocked there’s not a custom formula field! I need a third party app where I can take information put into Field A and then use a formula to pupulate the new answer or data in Field B. Simple.

It would also be able to pull a report daily, weekly, monthly - such as a sales report with that field as ONE of the fields I need in the columbs.

Help please!

@Scott_Gifford, yeah a 3rd party would be needed to do something like this. PlusThis has quite a few functions that will do this for you.
